For purposes of explanation, specific configurations and details are set forth in sufficient detail to provide a thorough understanding of the present application. However, it will also be apparent to one skilled in the art that the subject matter of the present application may be practiced without the specific details presented herein.
- Reference is first drawn to
FIGS. 1 to 6 , showing acutting insert 10 in accordance with the present application. Thecutting insert 10 is intended for use in milling cutting operations and may be made of a hard and wear-resistant material such as cemented carbide, by form-pressing and sintering carbide powders in a binder. - The
cutting insert 10 has two opposingidentical end surfaces 12 and aperipheral surface 14 extending between theend surfaces 12. Theend surfaces 12 can be considered, without loss of generality, to constitute anupper end surface 12′ and alower end surface 12″ of the cutting insert. Thecutting insert 10 is square-shaped in an end view thereof. Theperipheral side surface 14 includes fouridentical side surfaces 16 and fouridentical corner surfaces 18 at whichadjacent side surfaces 16 merge. As can be seenFIGS. 5 and 6 , in a side view of the cutting insert 10 theside surfaces 16 are parallelogrammatic in shape. Thecutting insert 10 has a central axis A and a throughhole 20 extending between theend surfaces 12. The through hole may be centered about central axis A. - The
cutting insert 10 has a median plane M located between theend surfaces 12 and passing through theperipheral surface 14. The median plane M may be perpendicular to theperipheral surface 14. The median plane M may be perpendicular to the central axis A. - Each
end surface 12 has fourcorners 22, two diagonally opposite loweredcorners 22′ and two diagonally opposite raisedcorners 22″. The loweredcorners 22′ are closer to the median plane M than the raisedcorners 22″. Eachcorner surface 18 extends between a given raisedcorner 20″ of one of the two opposing end surfaces 12 (e.g., theupper end surface 12′) and a given loweredcorner 20′ of the other of one of the two opposing end surfaces 12 (e.g., thelower end surface 12″). A diagonal line L passes through the loweredcorners 20′ of eachend surface 12. In other words, a diagonal line is associated with each end surface. Eachend surface 12 slopes from theraised corners 22″ to the diagonal line L associated with thatend surface 12. In an end view of the cutting insert 10 the central axis A passes through an intersection of the two diagonal lines L, it being understood that the diagonal lines L associated with the twoend surfaces 12′, 12″ do not intersect in three dimensions. - A
peripheral cutting edge 24 is formed at the intersection of eachend surface 12 and theperipheral surface 14. For eachend surface 12, theperipheral cutting edge 24 comprises fourmain cutting edges 26, formed by the intersection of theside surfaces 16 with theend surface 12 and fourcorner cutting edges 28, formed by the intersection of thecorner surfaces 18 with theend surface 12. Therefore, thecutting insert 10 is indexable with a total of eightmain cutting edges 26 and eightcorner cutting edges 28. Eachmain cutting edge 26 extends between a pair ofcorner cutting edges 28. Onecorner cutting edge 28 of each such pair ofcorner cutting edges 28 connecting to a commonmain cutting edge 26 is located at a lowered corner (22′) and the other corner cutting edge (28) of that pair is located at a raised corner (22″). In eachend surface 12, extending from theperipheral cutting edge 24 is arake surface 30 along which chips cut from a workpiece flow during a metal cutting operation. -
FIGS. 3 and 4 show views along the diagonal lines L for a given orientation of the cuttinginsert 10. As mentioned above, for the orientation of the cuttinginsert 10 as shown inFIG. 1 , oneend surface 12 will be referred to as anupper end surface 12′ and theother end surface 12 will be referred to as alower end surface 12″.FIG. 3 shows the view along the diagonal line L associated with theupper end surface 12′ and is referred to herein as a first corner view of the cutting insert. In the first corner view, theperipheral surface 14 has an upward-facing V-shape.FIG. 4 shows the view along the diagonal line L associated with thelower end surface 12″ and is referred to herein as a second corner view of the cutting insert. In the second corner view, theperipheral surface 14 has a downward-facing V-shape. The second corner view being a 90° rotation about the central axis A relative to the first side view. It is understood from the foregoing that cutting insert may have 180° rotational symmetry about central axis A. Both views are for the orientation of the cuttinginsert 10 as shown inFIG. 1 . As can be seen, fromFIGS. 3 and 4 theperipheral surface 14 has a V-shape in a view along the diagonal line L. The V-shapes seen inFIGS. 3 and 4 are identical in form to but with the “V” oriented in opposite directions. - Attention is now drawn to
FIGS. 7 and 8 showing amilling tool 32 in accordance with a specific application of the subject matter of the present application. Themilling tool 32 has an axis of rotation R and a plurality of insert pockets 34 in which the cutting inserts 10 are mounted and secured by means of ascrew 36. Eachinsert pocket 34 comprises abase wall 38 adjacent aside wall 40. Theside wall 40 is provided with two spaced apart side abutment surfaces 42 that abut a givenside surface 16 of the cuttinginsert 10. Thebase wall 38 is provided with two non-coplanar base abutment surfaces 44 that abut anon-operative end surface 12 of the cuttinginsert 10. - The cutting inserts 10 may be mounted such that they are alternately disposed with two different orientations of the operative
main cutting edge 26. Some of the cutting inserts 10′ may be oriented so their operativemain cutting edge 26′ presents a positive axial rake angle (illustrated also inFIG. 5 ) and the other cutting inserts 10″ may be oriented so their operativemain cutting edge 26″ present a negative axial rake angle (illustrated also inFIG. 6 ). - Consequently, each
end surface 12 of the cuttinginsert 10 in accordance with the subject matter of the present application has two main cutting edges 26 that can operate with a positive axial rake and two that can operate with a negative axial rake. Therefore, the cuttinginsert 10 has in total four main cutting edges 26 that can operate with a positive axial rake and four that can operate with a negative axial rake. - The cutting inserts 10 in accordance with the subject matter of the present application are clearly advantageous when both positive and negative axial rakes are required. A
single cutting insert 10 can be used to provide cutting edges with both positive and negative axial rake angles, a total of four of each kind. - Although the present invention has been described to a certain degree of particularity, it should be understood that various alterations and modifications could be made without departing from the scope of the invention as hereinafter claimed.
